Table A.1.
Analysis results on 26 featureless spectra of 18 blazars observed with Lick/KAST. They include one spectrum of 1RXS J035000.4+064053 for which we report Keck/ESI observations in Table 3 which resulted in its redshift measurement: z = 0.2730. The Lick/KAST spectrum has a S/N that is too low to confirm this result.
